HTMLSelectElement: checkValidity() method - Web APIs | MDN (original) (raw)

Baseline

Widely available

The checkValidity() method of the HTMLSelectElement interface returns a boolean value which indicates if the element meets any constraint validation rules applied to it. If false, the method also fires an invalid event on the element. Because there's no default browser behavior for checkValidity(), canceling this invalid event has no effect.

Syntax

Parameters

None.

Return value

Returns true if the element's value has no validity problems; otherwise, returns false.

Examples

In the following example, calling checkValidity() returns either true or false.

const element = document.getElementById("mySelect");
console.log(element.checkValidity());
